详解PHP中的序列化、反序列化操作

//序列化$str = serialize($r1);//保存到本地file_put_contents("文本文件路径",$str);//从本地取出$str2 = file_get_contents("文本文件路径");//反序列化为之前的对象$v1 = unserialize($str2);

<?php$v1 = 1;$v2 = 'abc';$v3 = array('a'=>1,'bb'=>2.2,'awd',true);$str1 = serialize($v1);$str2 = serialize($v2);$str3 = serialize($v3);//写入文本文件file_put_contents('./a1.txt', $str1);file_put_contents('./a2.txt', $str2);file_put_contents('./a3.txt', $str3);?>

<?php$s1 = file_get_contents('./a1.txt');$s2 = file_get_contents('./a2.txt');$s3 = file_get_contents('./a3.txt');$var1 = unserialize($s1);$var2 = unserialize($s2);$var3 = unserialize($s3);echo "<br/>var_dump($var1,$var2,$var3)";?>
